Answer:
y = ¼x + (-7/4)Step-by-step explanation:
find the gradient ( M)
M = y2- y1 ÷ x2-x1
M= -3 - (-1)÷(-5)-3 = ¼
thefind C in the equation (y=mx+c)
C = y-mx ( C = -1-¼(3)= -7/4(use in y and x values provided)
now replace the values you find in the equation (y=Mx+C)
final answer is
y = ¼x+(-7/4)y = ¼x + (-7/4) is the standard form for the line that passes through (3, −1) and (−5, −3)
What is Slope intercept form?y=mx=c is the slope intercept form of a line, m is the slope.
We need to find equation of line passing through (3, −1) and (−5, −3)
First we need to calculate slope 'm'.
slope m = y2- y1 / x2-x1
y2=-3, y1=-1, x2=-5, x1=3
m= -3 - (-1)/(-5)-3 = -2/-8=1/4
Equation of line, y=mx+c
find C in the equation (y=mx+c)
C = y-mx
C = -1-1/4(3)= -7/4
now replace the values you find in the equation (y=Mx+C)
y =1/4x-7/4
Hence y =1/4x-7/4 is the equation of line passes through (3, −1) and (−5, −3).

Part (i)
I'll use H in place of T to represent the heat of the object. That way there isn't a clash of variables lowercase t vs uppercase T.
The equation we're working with is updated to:
H(t) = 22 + a*2^(bt)
Plugging in t = 0 as the initial time value should lead to the temperature being H = 86 degrees Celsius.
So,
H(t) = 22 + a*2^(bt)
86 = 22 + a*2^(b*0)
86 = 22 + a*2^0
86 = 22 + a*1
86 = 22 + a
a+22 = 86
a = 86-22
a = 64
Answer: 64=====================================================
Part (ii)
We'll use the value of 'a' we found earlier. Plus we'll use the fact that H = 28 when t = 0.5 (since 30 min = 30/60 = 0.5 hr).
H(t) = 22 + a*2^(bt)
28 = 22 + 64*2^(b*0.5)
28-22 = 64*2^(0.5b)
64*2^(0.5b) = 6
2^6*2^(0.5b) = 6
2^(6+0.5b) = 6
log( 2^(6+0.5b) ) = log(6)
(6+0.5b)*log(2) = log(6)
6+0.5b = log(6)/log(2)
6+0.5b = 2.5849625
0.5b = 2.5849625-6
0.5b = -3.4150375
b = -3.4150375/(0.5)
b = -6.830075

Answer: 2
Step-by-step explanation: The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2

Answer:
Step-by-step explanation:
If x=9, then x^2=81, because 9*9=81. -x^2=81, because -9*-9=81, and (-x)^2=81, because -9*-9=81.
If x=6, then x^2=36, because 6*6=36. -x^2=36, because -6*-6=36, and (-x)^2=36, because -6*-6=36.
Answer:
Keep in mind that x has a coefficient of 1.
x = 9x² = 9² = 81
-x² = - 1 · 9² = -1 · 81 = -81
(-x)² = (-9)² = 81
x = -6x² = -6² = -36
-x² = - 1 · -6² = -1 · 36 = -36
(-x)² = (-1 · -6)² = 36

The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
The amount of calories in a cheeseburger increases by 121 for every one gram of fat. The calorie amount estimated by this model is 1.42 if there are zero grams of fat.
The amount of fat in a cheeseburger increases by 121 grams for every one calorie.
The fat amount estimated by this model is 1.42 grams if there are zero calories.
The amount of fat in a cheeseburger increases by 1.42 grams for every one calorie.
The fat amount estimated by this model is 121 grams if there are zero calories.
The amount of calories in a cheeseburger increases by 1.42 when there are zero grams of fat.
The calorie amount estimated by this model is 121 if there is one gram of fat.
Using linear function concepts, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which represents by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The explanatory variable fat is the input.The response variable calories is the output.The equation is:
[tex]y = 121 + 1.42x[/tex]
The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

The total cost after sales tax to fix Azar’s computer is represented by the expression 0.08 (55h) + 55h, where h represents the number of hours it takes to fix Azar’s computer.
What percentage sales tax is Azar being charged? Explain your answer using 1-2 sentences
What part of the expression represents the dollar amount of sales tax Azar must pay?
Answer:
these are 5 points look clearly.XD
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Given,
The total cost after sales tax to fix Azar’s computer is represented by the expression:
- 0.08 (55h) + 55h
where h represents the number of hours it takes to fix Azar’s computer.
We need to find out what percentage of sales tax is Azar being charged.
and what part of the expression represents the dollar amount of sales tax Azar must pay.
What represents sales taxes?It is mostly represented by a percentage.
We have,
100% = 100/100 = 1
50% = 50/100 = 1/2 = 0.5
25% = 25/100 = 1/4 = 0.25
20% = 20/100 = 1/5 = 0.2
We have,
- 0.08 (55h) + 55h
The sales tax is also charged according to the number of hours so,
In the expression 0.08 can be written as a percentage.
0.08 = 8 /100 = 8%
The percentage sales tax is 8%.
Now,
0.08 55(h) means the sales tax Azar must pay.
For 1 hour,
0.08 x 55 = 4.4 is the sales tax.
For 2 hours,
0.08 x (55x2) = 0.08 x 110 = 8.8.
And so on,
So,
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
Thus,
The percentage sales tax is 8%.
The part of the expression that represents the dollar amount of sales tax Azar must pay is 0.08 55(h).
